Season the steak with salt and pepper on both sides.

Spray a large skillet or grill pan with nonstick cooking spray. Heat over medium until hot but not smoking. Sear the steak, cooking 6-10 minutes per side, depending on thickness; the shoulder London broil will be thicker than the minute steak fillet.

Allow to rest for 10 minutes, and then slice thinly on the diagonal.

Separate the romaine lettuce leaves. Stack the leaves and chop into bite-sized pieces, to make about 12 cups chopped. Place into large bowl.

Add the carrot, scallion, cilantro, mint, and mandarin oranges. Toss the steak slices into the salad.

Squeeze the orange half over the salad.

In a small bowl, whisk the mayonnaise, teriyaki, ginger, lime juice, and sesame oil. Drizzle over the salad and toss to coat the steak and vegetables well.

Garnish with the noodles.
